Figure 5. Expression patterns of an unc-14::lacZ fusion gene. The Sall fragment of pR9.2 shown in Fig. 4 was subcloned in IacZ expression vector pPD22.04. This unc-14::lacZ fusion gene is capable of rescuing an unc-14 mutant. The transgenic worms were fixed and stained with an anti-LacZ antibody. (A) L2 worm head region. (H.G.) head ganglia. (B) The posterior part of the same worm. (T.G.) Tail ganglia. (C) A higher magnification picture of the middle-body region of an L2 worm. White arrows represent cell bodies of ventral neurons. Black arrowheads represent the ventral nerve cord. Bar, 50 um.
